As a potential eco-friendly biomass-based platform compound, ethyl levulinate has a carbonyl team and also an ester group, has excellent sensitivity, and can undergo different chemical reactions such as hydrolysis, decrease, condensation, and also nucleophilic enhancement. Making use of the benefits of the above responses, ethyl levulinate is not just utilized in industries such as solvents, scents, oil ingredients and also plasticizers, however likewise as important pharmaceutical and also chemical raw materials.

Ethyl Levulinate Uses
Ethyl levulinate is a food spice that is allowed to be used according to GB 2760-96.
Preparation of Ethyl Levulinate
1. Prep work of ethyl levulinate by direct esterification The direct prep work of levulinic acid esters by levulinic acid esterification has attracted much attention, particularly the target compound ethyl levulinate generated by the response of levulinic acid and ethanol. The reaction device is displayed in the figure.
In the preparation of ethyl levulinate, high activity, easy to separate, less pollution, recyclable strong acid catalysts as well as other green stimulants are generally used today. TiO2/SO2 -4 solid superacid catalyst (described as BST kind stimulant) with molecular sieve as the carrier, ethanol and levulinic acid as raw materials, V alcohol: V acid = 5:6, the stimulant dosage is 5% of the mass of levulinic acid, In an oil bath at 110 ° C for 1.5 h. After the reaction was finished, ethyl levulinate was obtained by distillation under minimized pressure, with a yield of 96.5%.
2. Acid-catalyzed alcoholysis conversion of biomass to prepare ethyl levulinate Under particular problems, ethyl levulinate can be prepared from biomass via catalytic alcoholysis. At present, there are a lot of research study records on the preparation of ethyl levulinate with alcoholysis of raw materials such as sugar, cellulose and wheat straw at home and also abroad.
3. Preparation of ethyl levulinate by alcoholysis of furfuryl alcohol Furfuryl alcohol is an important organic chemical basic material, which can be reduced from furfural. The furfuryl alcohol alcoholysis approach is to manufacture ethyl levulinate by home heating furfuryl alcohol under acidic problems, and also furfuryl alcohol is quickly polymerized under acidic conditions, so furfuryl alcohol requires to be added gradually to minimize its steady focus. The reaction process of preparing ethyl levulinate by alcoholysis of furfuryl alcohol is shown in the figure.
Experiments show that catalytic task: sulfuric acid > macroporous resin > gel material > molecular screen, the outcomes show that although ion exchange resin is made use of as driver, ethanol: furfuryl alcohol = 2.7: 1, the return is not the highest at 125 ° C for 5 hours, yet it can still Approximately 90%. Lange believes that the ion exchange resin with reduced focus has really high porosity, so it is not easy to form ether as a by-product.
